Patent number: 11470571Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A location server can estimate a coarse location of a mobile device using a localization technique other than a UWB localization technique. The localization technique can involve multiple wireless access points or other radio devices. The location server can define an area around the coarse location to identify a set of candidate anchors for UWB ranging. The set of candidate anchors can be disposed within the area and include at least a subset of the radio devices. The location server can modify the set of candidate anchors to create a modified set of candidate anchors that includes only UWB-enabled devices. The location server can select a primary anchor from the modified set of candidate anchors and send a command to cause a UWB ranging procedure to be initiated between the primary anchor and the mobile device.Type: GrantFiled: November 16, 2020Date of Patent: October 11, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Jerome Henry, Robert Edgar Barton, Matthew Aaron Silverman

Patent number: 11463283Abstract: This disclosure provides a split-path equalizer and a clock recovery circuit. More particularly, clock recovery operation is enhanced, particularly at high-signaling rates, by separately equalizing each of a data path and an edge path. In specific embodiments, the data path is equalized in a manner that maximizes signal-to-noise ratio and the edge path is equalized in a manner that emphasizes symmetric edge response for a single unit interval and zero edge response for other unit intervals (e.g., irrespective of peak voltage margin). Such equalization tightens edge grouping and thus enhances clock recovery, while at the same time optimizing data-path sampling. Techniques are also disclosed for addressing split-path equalization-induced skew.Type: GrantFiled: October 19, 2020Date of Patent: October 4, 2022Assignee: Rambus Inc.Inventors: Masum Hossain, Jared L.
